I need some help with troubleshooting my car. I just finished installing the pure stage 2 turbo, 3.5 bar and the XDI-35 fuel pump.
I took the car to the drag strip and it was great. When I drove it home it started to idle rough. I let it cool down over night and did a log this morning. Still really rough. I have new plugs on order but have not arrived yet. Can someone help me review these logs?
Car: 2014 N55 435i F33 EWG
Map 93 stage 2



3rd gear pull.

I was going to do that but it is sounding really bad. I have logs from the drag strip.
Here is one of them:

Miles since last plug change? Verify your charge pipe is still seated and/or intact...also verify your coils are all seated

Thanks I will check all that again.
Plugs have 20k on them. New ones will be here on Tuesday.

Once you install new plugs...consider re-gapping

No trouble codes?

This is what I now have this morning.
I check and the pipes are all on. So nothing came loose.

I just flashed it back to just the stage 2 93 octane. Seams to idle better so I am going to go do a 4th gear pull later today.

I was able to get a 3rd gear pull just now.

Can someone review this 3 gear pull. Could not do a 4th hear because of traffic but just looking for something not reading correctly.
It sounds like it is going to die when i idle. The whole car shakes.
I just updated the turbo, XDI and tmap 3.5. I did order new plugs but won't be here for a few days.

I pulled the first 4 plugs to see how bad they were.

Right around .028

doubtful that's the root of the issue...however, I'd consider closer to .20 - .22


I'd send log to PTF to rule out XDI and tune

I will see what they say. Thank you for your help.

Don’t change the gap on Bosch platinum plugs. They deteriorate and can break apart in the cylinder. If you want to run a smaller gap switch to NGK plugs.

They are on order and will have them on Tuesday.

Do you have a way to enable actual HPFP psi? I’m not a bm3 guy so forgive me if I’m missing something, but your throttle is barely opening during your second log. Normally this is due to fuel rail pressure issues.

Do you have an upgraded lpfp?

Yes I had to pick the XDI fuel pump in the tune then flash it. I updated the log tonight with a 3rd gear pull. It seams to run fine if I am on it but man if it is at idle the car shakes and sounds bad. To the point you don't want to drive it.
I check all the Connections from the turbo to the intake. Everything is solid. I went back to the normal map and still did not help.
Thinking about going back to the old tmap sensor to see if that changes anything.

Are you selecting 3.5 bar map in the flash options before flashing?

Yes I changed just the first one (pre throttle). Then flashed. I went in afterwards to make sure they were saved. I am going to do another log this morning of just the idle. I will post that.
